I Just purchased my first Emerson knife.. Now..here's the bad part..When the knife is half open, if you shake it, it sounds like a can of spray paint..this can't be normal. Sounds like something is loose somewhere.. Seems like I can move the blade a little as well..should I take it apart?? Not sure what to do..I really need the knife and don't have the time to send it to Emerson right now..should I just buy another knife to save time or can I fix the problem myself? Any help would be greatly appreciated.. By the way..it's a cqc-7 bw (not sure if that helps)
